The walls of three settlements were excavated to the South from the glassworks. The baroque monastery was built upon the Southern wing of the third room.

The permanent exhibition of graphic artist Kálmán Csohány was opened in 2001 in a monument building built in the 1870'ies. Since 1990 the general public had been able to find 50 works of the master in two museum rooms. However, thanks to the opening of the galery, now we can see about 150 individual works of the master. Kálmán Csohány wrote about himself in his autobiography as follows.

The building has three divisions: the portal leads ibto the kitchen, and the room opening to the North was served as a lard. Herein there were three pieces of grain container dug into the floor. These holes proved a real archaeological sensation, for almost the whole scale of th 15-16th century housekeeping instruments were discovered in hem. Possibly the news of the Turkish approach (1551) made the school master to flee and carefully hide his values in the holes.

The exhibition is arranged in the western wing of the first floor of the monastery. Visitors can follow up the most characteristic minerals and fossils, as well as the geografical conditions of their formation. There is an elefant found in the Salgótarján basin, as well as prehistoric plant imprints from Ipolytarnóc.
